MANUFACTURE OF FUEL.

No Drawing.

. have invented certain new and useful Improvements in and Relating to the Mannfacture of Fuel, of which the following is a specification.

This invention relates to the treatment of ordinary gas coke in order to render it easy of ignition and capable of free burning so that thus it may be used as a domestic-fuel in substitution of coal.

According to the invention I discharge the hot coke as it leaves the retort into a tank containing heavy tar oil or other suitable liquid hydrocarbons or other material on the surface of which is floated a layer of water whose thickness is determined for example by allowing 1 inch of water per cwt., of coke to be quenched, the amount of oil or hydrocarbons used being suflicient practically to cover the coke shot in. The lmpact of the red hot coke with the Water gives rise to violent ebullition, quenches the exterior of the coke but leaves the interior still hot. On reaching the oil the latter penetrates to the hot core and is partly vaporized and partly decomposed and is driven into the pores of the coke. The water is then run off from the top of the oil through a floating outlet or otherwise and the oil is drawn from the bottom of :the tank leaviiw'the coke still at a temperature of about a little over the boiling point of Water so that thus it quickly dries. Coke "so treated ignites easily and burns with a smokeless combustion.

Several hydrocarbons havin a flash point of over 250 F., might be used for the purpose of the invention but I prefer heavy tar oil as its high specific gravity insures the water remaining as a layer on the surface and the heavy tar oil itself is of such low Specification of Letters Patent.

commercial value as to be the cheapest material to use.

I am aware that it has before been proposed to spray coke with such oils, but if thecoke be hot this gives rise to ignition while if the coke be cold the lower portions of the mass are oily and unfitted for use. The plunging of coke into tar oil has also been su gested but here again if the coke be at a su 'ciently high temperature to obtain any useful effect the whole mass is liable to ignite.

What I claim as my inventionand desire to secure by Letters Patent. is

1. A process for the manufacture of fuel consisting in the immersion of hot coke in a liquid fuel over which floats a layer of liquid substance by which the coke on its exterior surface is cooled before passing into the liquid fuel.

2. A process for the manufacture of fuel consisting in the immersion of hot coke into liquid fuel of higher specific gravity than Water over which a layer of water floats substantially as described.

3. A process of manufacture of fuel consistin in the immersion of hot coke in heavy i l over which floats a layer of liquid substance by which the coke is cooled on its 1
